A Simple Nutrient Management Plan, NMP
This website is designed to provide a step-by-step process for developing a simple nutrient management plan. The material was developed to assist Montana's livestock producers in determining if they have enough land for manure application and developing their own nutrient management plan. Our intent was to provide information to help producers implement "best management practices" that are compliant, technically sound, economically feasible, and site-specific.
